You should never propose if you are not 100% sure the answer is yes. You talk about it before. The only thing that should be a surprise is where and how you propose.
To be fair — if I talked to my hypothetical pilot boyfriend and agreed I would marry him and then he proposes on a flight he pilots, in front of all the passengers, I might say No no matter what we discussed previously. Because that would certainly make me question the whole relationship.
There can never be a 100% sure while the where and how to propose is still open, since it includes a lot of scenarios that range from uncomfortable to batshit insane.
By hypothetical do you mean AI boyfriend and by say no do you mean your just worried about the plane being distracted? It didn't go well for Bender I doubt it would for you.
I think this only makes sense if the engaging couple are like super close with the wedding pair. And even then it depends a lot on the personalities of the couple getting married
Because marriages and weddings are to show the community you're together. That's the whole point.
Some people are a bit more extrovert about it than others, as in all things.
I was at a hockey game last weekend where a guy proposed. The camera man couldn’t even be bothered to walk down and catch their faces so all we saw was the back of their heads on the Jumbotron, I thought it was hilarious.
"Ehhh, this is your captain speaking, ehhh, we're gonna be experiencing some turbulence as the plane heads straight down into the ocean, ehhh, please remain seated while the seat belt light is on."
Because if the girl said 'no', then the answer is obviously 'no'. But the thing is she is not gonna say no. She would never say 'no', because of the implication.
